SCOPE 1.1 The material covered in this contract/purchase order will be used in a crucial shipboard system. The use of incorrect or defective material would create a high probability of failure resulting in serious personnel injury, loss of life, loss of vital shipboard systems, or loss of the ship itself. Therefore, the material has been designated as SPECIAL EMPHASIS material (Level I, Scope of Certification, or Quality Assured) and special control procedures are invoked to ensure receipt of correct material. 2. APPLICABLE DOCUMENTS 2.1 Order of Precedence - In the event of a conflict between the text of this contract/purchase order and the references and/or drawings cited herein, the text of this contract/purchase order must take precedence. Nothing in this contract/purchase order, however, must supersede applicable laws and regulations unless a specific exemption has been obtained. 2.2 Applicable Documents - The document(s) listed below form a part of this contract/purchase order including modifications or exclusions. 2.2.1 "Document References" listed below must be obtained by the Contractor. Ordering information is included as an attachment to this contract/purchase order. 2.3 Specification Revisions - The specification revisions listed under "Docu ments References" below are the preferred revision. Older and/or newer r evisions are acceptable when listed within Contract Support Library Reference Number CSD155 in ECDS (Electric Contractor Data Submission) at: ht tps://register.nslc.navy.mil/. This is to allow Contractors to use certain acceptable older specification revisions to purge their existing stock of material certified to those older revisions or to use newer specification revisions when material is certified to newly released revisions,without requiring the submittal of waiver/deviation requests for each specification revision on every contract. Revisions of specifications reflecting editorial and/or re-approval (e.g. E2009, R2014, etc.) are considered inconsequential, but are acceptable when their revisions are listedwithin CSD155 or elsewhere within this contract.

Material certification test reports shall include the class, form, condition, grade, type, finish, and/or composition, as applicable, of the material supplied. 3.19.2 Re-identification and re-certification of material is required when the material is subjected to a process which alters it's properties. If the starting material or raw stock is processed in a manner that will not affect its chemical composition or mechanical properties, the original certifications for the chemical composition and mechanical properties, as required by the material specification, are acceptable. Re-certification of the chemical or mechanical properties is required if a process is used during fabrication that alters the original properties of the material (e.g. alloying, heat treating, or forming). In these instances, the properties of the material must be re-determined and documented to reflect the altered condition. The altered material shall be uniquely re-identif...
